Error while running in Headless mode #201

Hi,

I'm running NetLogo on a cluster and run into the following error:

I tried different Netlogo versions (everything since 6.0) and also different different jdks. Anybody an idea how to solve this?

@egonzales2000 Which Java version are you running NetLogo with? That looks like it might be caused by running NetLogo with a version greater than Java 8 (the only version NetLogo 6.2.2 supports).

egonzales2000 commented 2 years ago

Hi, thanks so much. With jdk 8 everything works as expected. Just wasted 2 days for that (Did not think much on further testing jdks as Netlogo runs perfectly with e.g. jdk 16, it's just the nw extension which make problems and I thought this is related to #194)

@egonzales2000 Oof, sorry to hear about your wasted time, but I'm glad you got it resolved.
